The same way that drinking tea can have many benefits for your health, a good soak in the right tea blend can also be absorbed through your skin and produce similar benefits. Bath teas combine essential oils, herbs and salts to aid in detoxification, promotes skin health and moisturizes. Fill the reusable tea bag with the tea and place under the faucet while the bathtub is filling. If you prefer, add the tea directly to your bathwater.
